Three men have been accused of filling shutter doors at Ibrox Stadium with expanding foam.
Steven Breslin, 24, Michael McKay, 23, and Ryan Cross, 19, deny the charge of malicious mischief at Glasgow Sheriff Court.
The alleged offence is said to have taken place on April 3, 2022.
Later that day, Celtic went on to beat their Glasgow rivals Rangers 1-2.
Court papers state the three men “maliciously damaged several shutter doors by spraying expanding foam on them.”
Breslin, of Linwood, Renfrewshire, McKay, of Johnstone, Renfrewshire and Cross, of Dunfermline, were due to stand trial on Tuesday.
There was a defence motion to adjourn and a new trial date was set by Sheriff Iain Nicol.
The trio will stand trial in January 2023.
Their bail was continued in the meantime.
